RELATED APPLICATIONS

This application is a divisional application of U.S. Ser. No. 09/353,701, filed Jul. 14, 1999, now U.S. Pat. No. 6,492,301, now allowed and herein incorporated by reference, which claims priority to German application No. 198 32 017.5, filed on Jul. 16, 1998.

The invention relates to the technical field of crop protection agents and relates in particular to herbicidal compositions comprising compounds of the formula I

-   -   in which     -   R¹ is (C₁-C₈)-alkyl, (C₃-C₄)-alkenyl, (C₃-C₄)-alkynyl or         (C₁-C₄)-alkyl, which is mono- to tetrasubstituted by radicals         from the group consisting of halogen and (C₁-C₂)-alkoxy;     -   R² is I, or CH₂NHSO₂CH₃;     -   R³ is methyl or methoxy; and     -   z is N or CH;         and/or their salts, which are highly suitable, for controlling         weeds in rice which have hitherto been difficult to control with         individual herbicides, in particular grass-like, dicotyledonous         and/or cyperaceae-like weeds in rice or transgenic crops of         rice.

For the relevant prior art, the following publications may be mentioned:

WO 92/13845 (PCT/EP92/00304)=D1,

WO 95/10507 (PCT/EP94/03369)=D2,

WO 96/41537 (PCT/EP96/02443)=D3 and

WO 98/24320 (PCT/EP97/06416)=D4.

D1 discloses iodinated arylsulfonylureas of the formula I and salts thereof,

where the formula I embraces a large number of possible individual compounds, owing to the extensive and broad definition of the radicals Q, W, Y, Z, R, R¹, R² and R³.

D1 indicates, in a general manner, that the compounds of the formula I may be used together with other herbicides. This indication is followed by an exemplary enumeration of more than about 250 different standard active compounds. Information about a particular reason and purpose of joint application is, except for the fact that the substances are mentioned, not given in D1, nor a motivation for targetted selection and combination of certian active compounds.

D2 discloses phenylsulfonylureas of the formula 2 and salts thereof

where, once more, the formula 2 embraces a very large number of possible individual compounds, owing to the extensive and broad definition of the radicals A, W, R¹, R², R³, R⁴, R⁵, R⁶ and R⁷.

In Table 1 of D2, compounds of the formula (2a) are listed

where the examples Nos. 105, 209, 217, 395, 399, 403, 407, 497 and 536 relate to those compounds of the formula 2a in which Z is CH, X and Y is methoxy, R⁷ is hydrogen, R¹ is alkoxycarbonyl, R⁴ is hydrogen and R⁵ is a radical which contains a sulfonyl group (SO₂CH₃, SO₂NHCH₃, SO₂N(CH₃)₂, SO₂N(CH₃)₂, SO₂CH₂F, SO₂CF₃, SO₂C₂H5, SO₂—n—C₃H₇,preferably SO₂CH₃).

D2 gives biological examples for the compounds mentioned individually above in that, in a general manner, it is mentioned that the compounds of Examples 105, 217 and 536—in addition to a large number of other compounds—have very good activity against harmful plants such as Sinapis alba, Stellaria media, Chrysanthemum segetum and Lolium multiflorum when applied pre- or post-emergence at an application rate of from 0.3 kg to 0.005 kg of active substance per hectare. In the abovementioned international laid-open publication, the crop plant compatibility of the compounds of the formula 2 or 2a is not demonstrated by any examples.

Furthermore, D2 indicates, in a general manner, the possibility of using the compounds of the formula 2 together with other herbicides. This indication is followed by an exemplary list of more than about 250 different standard active compounds. The proposed combinations seem to have been given more or less at random, and they do not teach anything that exceeds the fact that herbicides can be combined in principle.

D3 discloses herbicidal compositions comprising

-   A) at least one herbicidally active compound from the group of the     substituted phenylsulfonylureas of the formula 3     in which     -   R¹ is (C₁-C₈)-alkyl, (C₃-C₄)-alkenyl, (C₃-C₄)-alkynyl or         (C₁-C₄)-alkyl, which is mono- to tetrasubstituted by radicals         from the group consisting of halogen and (C₁-C₂)-alkoxy         and -   B) at least one herbicidally active compound from the group of the     compounds consisting of -   Ba) herbicides that are selective in cereals and/or in maize against     grasses, -   Bb) herbicides that are selective in cereals and/or maize against     dicotyledonous plants, -   Bc) herbicides that are selective in cereals and/or maize against     grasses and dicotyledonous plants and -   Bd) herbicides that are nonselective in non-crop land and/or     selective in transgenic crops against wheat-grasses and broad-leaved     weeds.

The particular combinations that are mentioned are synergistic, the area of use is limited to cereals and maize.

D4 discloses combinations comprising:

-   A) at least one compound from the group of the substituted     phenylsulfonylureas of the formula 4 and their agriculturally     accepted salts     in which     -   R¹ is (C₁-C₈)-alkyl, (C₃-C₄)-alkenyl, (C₃-C₄)-alkynyl or         (C₁-C₄)-alkyl, which is mono- to tetrasubstituted by radicals         from the group consisting of halogen and (C₁-C₂)-alkoxy         and -   B) at least one herbicidally active compound from the group of the     compounds consisting of -   Ba) herbicides which are selective in cereals against grasses, -   Bb) herbicides which are selective in cereals against dicotyledonous     plants, -   Bc) herbicides which are selective in cereals against grasses and     dicotyledonous plants and -   Bd) herbicides which are nonselective in non-crop land or in     perennial crops (plantations) and/or selective in transgenic crops     against wheat grasses and broad-leaved weeds.

In particular, combinations with fenoxaprop, fenoxaprop-P, isoproturon, diclofop, clodinafop, mixtures of clodinafop and cloquintocet, chlortoluron, methabenzthiazuron, imazamethabenz, tralkoxydim, difenzoquat, flamprop, flamprop-M, pendimethalin, mecoprop, mecoprop-P, MCPA, dichlorprop, dichlorprop-P, 2,4-D, dicamba, fluroxypyr, ioxynil, bromoxynil, bifenox, fluoroglycofen, lactofen, fomesafen, oxyfluorfen, ET-751, azoles according to WO 94/08999, F 8426, diflufenican, bentazon, metribuzin, metosulam, flupoxam, prosulfocarb, flurtamone, amidosulfuron, metsulfuron, tribenuron, thifensulfuron, triasulfuron, chlorsulfuron, sulfonylureas according to WO 94/10154, sulfonylureas according to WO 92/13845, flupyrsulfuron (DPX-KE459), MON 48500, sulfosulfuron (MON37500), glufosinate, glufosinate-P or glyphosate are known.

Most of the sulfonylureas known from D1 and D2 according to the formulae 1 and 2 have useful to good activity against a broad spectrum of mono- and dicotyledonous harmful plants of economic importance, and even weeds which are encountered under the specific cultivation conditions in rice, such as, for example, Sagittaria, Alisma, Eleocharis, Scirpus, Cyperus etc., are controlled with the aid of active compounds of the formulae 1, 2 and 3; however, for optimum control of thee spectrum of mono- and dicotyledonuos weeds encountered in agricultural practice especially in rice, the individual active compounds are frequently insufficient. Moreover, the synergistic combinations of D3 or D4 can generally not be used with above-average success in rice. At least, this could not be expected with a more than average probability, in particular because the useful plant rice is, to a not unconsiderable extent, damaged by most of the combinations known from D3 or D4, so that these are not suitable for use in crops of rice.

Moreover, there exist, in particular in rice, a number of economically very important monocotyledonous weeds, such as, for example, primarily Echinochloa crus-galli, Ischaemum ssp. or Leptochloa which cannot be controlled in a satisfactory manner by using just the prior art rice herbicides or mixtures thereof. In particular from the rice crops in Japan and Southeast Asia, we know weeds such as Sagittaria spp., Eleocharis spp., for example Eleocharis kuroguwai, Cyperus serotinus, Scirpus juncoides, but also other weed species, which predominantly germinate from resting organs in the soil and are therefore more difficult to control than weeds which germinate from seeds, and also broad-leaved species which are not simple to control in an optimum manner in the entire width of the weed spectrum.

Furthermore, resistant species (inter alia of Cyperus ssp. or Echinochloa ssp.) which in many cases can no longer be controlled with individual active compounds and even with customary combinations are found increasingly.

With respect to the prior art mentioned and discussed herein, it was therefore the object of the invention to provide mixtures having herbicidal activity to enable the practitioner to control the weed spectrum or individual weed species which are difficult to control in rice with a single application or a few applications of herbicides. Furthermore, the mixtures of essentially known herbicidally active compounds are intended to close so-called “activity gaps” and, if possible, to reduce simultaneously the application rates of the individual active compounds. Moreover, it was the object to provide combinations which permit a very long duration of action to be obtained. Finally, the combinations are also intended to permit the effective control of resistant species.

Surprisingly, it has been found that these objects, inter alia, are achieved by herbicidal compositions having the features of claim 1. Accordingly, the invention provides herbicidal compositions, comprising

-   A) at least one herbicidally active compound from the group of the     substituted phenylsulfonylureas of the formula I and their     agriculturally accepted, i.e. acceptable and compatible, salts     in which     -   R¹ is (C₁-C₈)-alkyl, (C₃-C₄)-alkenyl, (C₃-C₄)-alkynyl or         (C₁-C₄)-alkyl, which is mono- to tetrasubstituted by radicals         from the group consisting of halogen and (C₁-C₂)-alkoxy;     -   R² is I or CH₂NHSO₂CH₃;     -   R³ is methyl or methoxy; and     -   Z is N or CH;         and -   B) at least one herbicidally active compound from the group of the     compounds consisting of -   Ba) herbicides which are selective in rice, mainly against grasses, -   Bb) herbicides which are selective in rice, mainly against     dicotyledonous harmful plants and cyperaceae, -   Bc) herbicides which are selective in rice, mainly against     cyperaceae,     and -   Bd) herbicides which are selective in rice, mainly against grasses     and dicotyledonous harmful plants and also against harmful     cyperaceae plants,     -   with the proviso that     -   i) compositions comprising -   A′) at least one compound from the group of the substituted     phenylsulfonylureas of the formula I′ and their agriculturally     accepted salts     in which     -   R¹ is (C₁-C₈)-alkyl, (C₃-C₄)-alkenyl, (C₃-C₄)-alkynyl or         (C₁-C₄)-alkyl, which is mono- to tetrasubstituted by radicals         from group consisting of halogen and (C₁-C₂)-alkoxy,     -   in combination with -   B′) fenoxaprop, pendimethalin, nicosulfuron, mecoprop, MCPA, 2,4-D,     dicamba, acifluorfen, azoles of the formula III     in which     -   R¹ is (C₁-C₄)-alkyl,     -   R² is (C₁-C₄)-alkyl, (C₁-C₄)-alkylthio or (C₁-C₄)-alkoxy, each         radical of which may be substituted by one or more halogen         atoms, or     -   R¹ and R² together form the group (CH₂)_(m) where m=3 or 4,     -   R³ is hydrogen or halogen,     -   R⁴ is hydrogen or (C₁-C₄)-alkyl,     -   R⁵ is hydrogen, nitro, cyano or one of the groups —COOR⁷,         —C(═X)NR⁷R⁸ or —C(═X)R¹⁰,     -   R⁶ is hydrogen, halogen, cyano, (C₁-C₄)-alkyl, (C₁-C₄)-alkylthio         or —NR¹¹R¹²,     -   R⁷ and R⁸ are identical or different and are hydrogen or         (C₁-C₄)-alkyl, or     -   R⁷ and R⁸ together with the nitrogen to which they are attached         form a saturated 5- or 6-membered carbocyclic ring,     -   R¹⁰ is hydrogen or (C₁-C₄)-alkyl, where the latter may be         unsubstituted or substituted by one or more halogen atoms, and     -   R¹¹ and R¹² are identical or different and are hydrogen,         (C₁-C₄)-alkyl or (C₁-C₄)-alkoxycarbonyl, where     -   R¹¹ and R¹² together with the nitrogen to which they are         attached may form a 3-, 5- or 6-membered carbocyclic or aromatic         ring in which one carbon atom may optionally be replaced by an         oxygen atom, bentazon, metsulfuron, triasulfuron, ioxynil,         acetochlor, metolachlor, oxyfluorfen or KIH-2023, as the only         herbicidally active compounds         and     -   ii) compositions which comprise -   A″)at least one compound from the group of the substituted     phenylsulfonylureas of the formula I″ and their agriculturally     accepted salts     in which     -   R¹ is (C₁-C₈)-alkyl, (C₃-C₄)-alkenyl, (C₃-C₄)-alkynyl or         (C₁-C₄)-alkyl, which is mono- to tetrasubstituted by radicals         from the group consisting of halogen and (C₁-C₂)-alkoxy     -   in combination with -   B″)fenoxaprop, pendimethalin, mecoprop, MCPA, 2,4-D, dicamba, a     compound of the abovementioned formula III, bentazon, triasulfuron,     ioxynil, metosulam, oxyfluorfen or metsulfuron as the only     herbicidally active compounds, are excluded.

The combinations according to the invention of herbicidally active compounds of types A and B permit, in a particularly advantageous manner, the control of the weed spectrum required by the practitioner to be achieved, and even individual species which are difficult to control are covered. Furthermore, using the combinations according to the invention, it is possible to reduce the active compound application rates of the individual combination partners contained in the combination considerably, permitting more economical problem solutions by the user.

Finally, it was surprisingly possible to achieve activity increases which exceed the expected degree, and the herbicidal compositions of the invention consequently displayed extensive synergistic activities.

Besides, it is also possible to control many resistant species in an excellent manner.

The boundary conditions i) and ii) (disclaimers with respect to product protection) take into account prior art combinations; however, these previously published combinations did not permit any conclusions with respect to the suitability of the combined preparations in rice applications to be drawn.

Specifically, the disclaimer i) avoids the combinations of one or more type A compounds and a type B compound which are already known from D3, their area of use unambiguously being different from the use of the combinations according to the present invention, and the subject matter of D3 and the present invention therefore being clearly differentiated from one another. While D3 describes combinations with herbicides for use in cereals or maize, the present invention relates to combinations for use in rice.

The disclaimer ii) defines the novelty with respect to D4, which relates to combinations having a type B compound for use in cereals. Here, likewise, the intended uses of the combination are clearly different from the intended uses in accordance with the present invention.

The compounds of type A (formula I) can form salts in which the hydrogen of the —SO₂—NH— group is replaced by an agriculturally suitable cation. These salts are, for example, metal salts, in particular alkali metal salts (for example Na or K salts) or alkaline earth metal salts, or else ammonium salts or salts with organic amines. Salt formation can also be achieved by adding a strong acid to the heterocycle moiety of the compounds of the formula I. Acids which are suitable for this purpose are, for example, HCl, HNO₃, trichloroacetic acid, acetic acid or palmitic acid.

Particularly advantageous type A compounds are those in which the salt of the herbicide of the formula (I) is formed by replacing the hydrogen of the —SO₂—NH— group by a cation from the group of the alkali metals, alkaline earth metals and ammonium, preferably sodium.

If the compounds of the formula I contain one or more asymmetric carbon atoms or else double bonds, which are not specifically indicated in the formula, they nevertheless belong to the type A compounds. All possible stereoisomers, such as enantiomers, diastereomers, Z and E isomers, defined by their specific spatial form are embraced by the formula I and can be obtained from mixtures of the stereoisomers by customary methods, or else by stereoselective reactions in combination with the use of stereochemically pure starting materials. The abovementioned stereoisomers, both in pure form and as mixtures, can accordingly be used according to the invention.

In a first distinguished variant of the invention, compounds of group Aa) are of particular interest as combination partners of type A for the combination of the invention, these compounds being compounds of the formula I in which R¹ is (C₁-C₈)-alkyl, (C₃-C₄)-alkenyl, (C₃-C₄)-alkynyl or (C₁-C₄)-alkyl, which is mono- to tetrasubstituted by radicals from the group consisting of halogen and (C₁-C₂)-alkoxy, R² is iodine, R³ is methyl and Z is N.

In principle, the phenylsulfonylureas of the formula I which carry iodine substituents in the 4-position of the phenyl ring are included, for example, in the formula 1 from WO 92/13845, and their suitability as synergism partners for herbicides to be used in cereals or maize is likewise already part of the prior art (cf. D3); however, their excellent suitability for use as combination partners for synergistic mixtures with other herbicides, which are used in rice, is not disclosed in the prior art. In particular, there are no indications in the published literature that combinations of compounds of group Aa), i.e. the relatively limited and clearly defined group of the 4-iodo-2-[3-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)ureidosulfonyl]benzoates, which are optionally present in the form of their salts, with rice herbicides have such an exceptional rank in the control of the most important harmful plants in rice crops. Here, it also has to be taken into consideration, in particular, that using a combination in crops of maize or cereals does not allow an extrapolation to the effect in crops of rice. Even if the compounds of group Aa) on their own are suitable for controlling harmful plants and rice, it is not possible to predict with a good or even some chance of success whether combinations with other rice herbicides permit, in the control of harmful plants, activity increases which exceed the additive activity.

Combination partners of type A which are of great interest for the combinations of the invention are compounds or their salts of group Aa) in which in the formula I R¹ is methyl, ethyl, n- or isopropyl, n-, tert-, 2-butyl or isobutyl, n-pentyl, isopentyl, n-hexyl, isohexyl, 1,3-dimethylbutyl, n-heptyl, 1-methylhexyl or 1,4-dimethylpentyl, R²is iodine, R³ is methyl and Z is N.

In a particularly preferred embodiment, the herbicidal compositions according to the invention comprise a type A compound from group Aa) of the formula I or their salt, where R¹ is methyl, R² is iodine, R³ is methyl and Z is N.

A special combination partner is the compound A1) methyl 4-iodo-2-[3-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)ureidosulfonyl]benzoate:

A combination partner which, in certain cases, is even more advantageous is the sodium salt of the compound A1) which is to be referred to as A1*).

In a further embodiment of the invention, preference is given to using sulfonylureas of the formula I which carry a methylsulfonylamidomethyl substituent in the 5-position of the phenyl ring as compounds of type A). The group Ab) is formed by compounds of the formula I in which R¹ is (C₁-C₈)-alkyl, (C₃-C₄)-alkenyl, (C₃-C₄)-alkynyl or (C₁-C₄)-alkyl, which is mono- to tetrasubstituted by radicals from the group consisting of halogen and (C₁-C₂)-alkoxy, R² is CH₂NHSO₂CH₃, R³ is methoxy and Z is CH.

The specific sulfonylureas of group Ab) are, in combination with other herbicides of type B), outstandingly suitable for controlling weed species which are difficult to control in crops of rice effectively. In particular, unexpected specific activity effects against resistant harmful grasses are achieved here.

Of particular interest for the combinations of the invention are, as combination partners of type A compounds of the general formula I from group Ab) or their salts in which R¹ is methyl, ethyl, n- or isopropyl, n-, tert-, 2 butyl or isobutyl, n-pentyl, isopentyl, n-hexyl, isohexyl, 1,3-dimethylbutyl, n-heptyl, 1-methylhexyl or 1,4-dimethylpentyl, R² is CH₂NHSO₂CH₃, R³ is methoxy and Z is CH.

In a very particularly preferred embodiment, the herbicidal compositions according to the invention comprise a type A compound from group Ab) of the general formula I or a salt thereof in which R¹ is methyl, R² is CH₂NHSO₂CH₃, R³ is OCH₃ and Z is CH.

Particular combination partners include the compounds A2):

and A3)

The combinaton partners of type B are generally standard herbicides; however, they have been selected using certain criteria. Thus, without exception they are herbicides which are selective in rice against undesirable plants. The harmful plants which are to be controlled here especially include grasses and dicotyledonous plants/cyperaceae. The notation “dicotyledonous plants/cyperaceae” is meant to express that the activity is against dicotyledonous plants and cyperaceae, but that the activity against dicotyledonous plants is in the foreground.

With respect to the activity of the standard herbicides of type B, it is possible to categorize them with respect to which plants are mainly controlled.

Thus, some of the type B herbicides are predominantly, or almost exclusively, active against grasses (subgroup Ba)), others are mainly active against dicotyledonous plants and cyperaceae (subgroup Bb)), others are mainly active against cyperaceae (subgroup Bc)), and another group shows activity both against grasses and against dicotyledonous plants/cyperaceae (subgroup Bd)).

In each case, however, an optimized activity spectrum results for the combination according to the invention by complementation and intensivation of the herbicidal properties of the compounds of type A.

Considering what was said above, a particular embodiment of the herbicidal composition of the invention comprises, as herbicides of type B, one or more herbicides from the group Ba) which are selective in rice against grasses, which includes herbicidally active anilides, in particular chloroacetanilides, thiocarbamates, quinolincarboxylic acids, cyclohexanediones and cyclohexanedione oximes, tetrazoles, organophosphorus compounds, 2-(4-Aryloxy-phenoxy)propionic acids, preferably their esters, ureas, pyridinecarbothioates, butyramides, menthyl benzyl ethers and triazoles.

In another very particularly advantageous embodiment, the herbicidally active mixture of the invention comprises, as herbicides of type B, one or more herbicides, which are selective in rice against grasses, from the group consisting of

The abovementioned compounds B1) to B8) are anilides some of which belong to the subgroup of the chloroacetanilides (compounds B1) to B4) ). The compounds B1) to B8) of the subgroup Ba) are mainly active against harmful grasses.

Specifically, the abovementioned herbicides B1) to B8) are directed against grasses, for example annual grasses. In addition, butachlor also covers broad-leaved weeds in rice, likewise butenachlor, which can additionally be used against aquatic weeds in rice; thenylchlor controls in particular Echinochloa spp; whereas Pretilachlor is active against numerous seeds.

Mefenacet is active in particular agaginst Echinochloa crus galli; the activity spectrum of naproanilide, propanil and etobenzanide covers especially: broad-leaved and grass-like weeds such as Amaranthus retroflexus, Digitaria spp., Echinochloa spp., Panicum spp., Setaria spp.; Bay Foe 5043 acts against a wide spectrum of grasses.

The compounds B9) to B12) are thiocarbamates whose activity unfolds best when controlling grasses in rice, mainly Echinochloa crus galli in rice (B9)), broad-leaved and grass-like weeds in rice, in particular Echinochloa spp. (B10)), monocotyledonous and annual broad-leaved weeds in rice, in particular Echinochloa, Leptochloa, Cyperus spp (B11)), annual and perennial grasses in rice, in particular Echinochloa oryzicol, Cyperus difformis, Monochoria vaginalis, Digitaria ciliaris, Setaria viridis (B12)).

B13) is a representative of the quinolinecarboxylic acids and is preferably employed for controlling grass-like weeds (Echinochloa spp., Aeschynomene spp., Sesbania spp.) and other weeds in rice.

B14) and B14a) are cyclohexanediones which, in the context of the combinations according to the invention, can surprisingly also be employed in rice against broad-leaved weeds and grasses.

In the wider sense, B15) and B16) also belong to the group of the cyclohexanediones. In particular, they are cyclohexanedione oximes which are preferably used for controlling annual and perennial grasses by the post-emergence method. It is particularly surprising, especially for B15) and B16) that, in combination with type A) compounds, an excellent tolerance in rice applications is achieved, something which is generally not the case when B15) or B16) are applied alone.

The tetrazoles also belong to the group Ba), and they act especially against grasses in rice. An important representative having the abovementioned chemical structure is the compound B17).

A further interesting subgroup of the subgroup Ba) are the organophosphorus compounds. B18) is preferably employed for controlling annual grasses and seeds in rice. B19) has a comparable activity spectrum, i.e.: annual grasses and seeds in rice.

The group Ba) furthermore includes the family of the herbicidally active 2-(4-aryloxyphenoxy)propionic acids. An important representative is B20) whose preferred area of use is against grasses in rice. B21) is likewise employed in the combinations of the invention, usually for controlling annual and perennial grasses. In the context according to the invention, it may also be particularly favorable to apply B20) and/or B21) together with a compound which additionally acts as safener, such as, for example, B22). Of particularly great interest are combinations according to the invention with B22). B22) acts, as acetyl-CoA carboxylase inhibitor, mainly against grasses and is, owing to the different metabolism of rice and weed, particularly well tolerated in rice applications.

Furthermore, the group Ba) includes the family of the herbicidally active ureas. An important representative of this chemical family is the compound B23). It is preferably active against annual and perennial grasses.

Furthermore of interest are the pyridinedicarbothioates, for example the compound B23), being active mainly against annual grasses and broad-leaved weeds in rice.

Another chemical subgroup of the group Ba) relates to the butyramides; particular emphasis is given to the compound B25). Combinations with B25) have proved to be highly suitable for controlling sedges, in particular Echinochloa spp., Eleocharis acicularis and Scirpus juncoides and some broad-leaved weeds in paddyfield rice and upland rice.

Also a member of group Ba) is the chemical grouping of the menthyl benzyl ethers. An important element of this group is the compound B26). It shows excellent activity against weeds in rice, such as Echinochloa spp., Monochoria vaginalis, Cyperus difformis.

Triazoles likewise have proved, as members of subgroup Ba) and together with compounds of the A type, to be most suitable for suppressing undesirable plant growth, in particular of annual and perennial weeds in paddy rice, such as Echinochloa oryzicola and Cyperus difformis.

Even though the representatives of the group Ba) have relatively different chemical structures, they still form a homogeneous subgroup, owing to their activity spectrum and to the fact that they are synergists for the compounds of the formula I.

Other compositions which are embraced by the invention are those comprising herbicides of type B from the subgroup Bb) . Here, it is particularly advantageous to use one or more herbicides which are selective in rice mainly against dicotyledonous plants and in some cases also against cyperaceae from the group comprising herbicides of the type of the aryloxyalkylcarboxylic acids and dicamba, nitrodiphenyl ethers, azoles and pyrazoles, sulfonylureas, benzonitriles, pyridinecarboxylic acids and triazoles.

Of particular interest are here herbicidal compositions which, as compound of type B, contain one or more compounds which are selective in rice against dicotyledonous plants and in some cases also cyperaceae, selected from the group consisting of the herbicides

From among the type B compounds showing selectivity in rice and being active against dicotyledonous plants and in some cases against cyperaceae {subgroup Bb) with the herbicidally active compounds B28)-B38) and their customary derivatives}, the combination partners B28) to B33), in each case on their own or else in combination with others, are extraordinarily suitable for use as component of a herbicidal composition according to the invention.

Thus, inter alia, the aryloxyalkylcarboxylic acids B28) to B31) are tolerated very well, and they also cover gaps in the weed spectrum to be controlled in an excellent manner.

Emphasis should furthermore be given to the compounds B34) and B35) which, as sulfonylurea compounds, are extraordinarily effective in the control of dicotyledonous plants/cyperaceae which are difficult to control by compounds of type A.

A third subgroup of compounds which, when admixed with compounds of type A, permit the production of herbicidal compositions having excellent properties is the subgroup Bc) of the herbicides which are selective in rice, mainly against cyperaceae. Type B substances having this activity profile are preferably found in the chemical substance classes of the ureas and benzofuranyl compounds, or they are present in the form of triclopyr or bentanzon.

Thus, a further advantageous embodiment of the invention comprises, as herbicide of type B,

-   B39) bentazon     -   3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one-2,2-dioxide         Pesticide Manual, 10th Ed. 1994, pp.90-91, -   B40) triclopyr     -   [(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid, preferably as         triclopyr, triclopyr-butotyl, triclopyr-triethylammonium,         Pesticide Manual, 10th Ed. 1994, pp.1015-1017, -   B41) benfuresate     -   2,3-dihydro-3,3-dimethylbenzofuran-5-yl ethanesulfonate         Pesticide Manual, 10th Ed. 1994, pp.81-82         and/or -   B42) daimuron     -   N-(4-methylphenyl)-N′-(1-methyl-1-phenylethyl) urea Pesticide         Manual, 10th Ed. 1994, pp.275-276.

All the compounds B39) to B42) are herbicides which are selective in rice and which, with respect to the spectrum of the harmful plants to be controlled, meet the abovementioned profile of requirements. B41) in particular is a benzofuranyl compound having a pronounced activity against grasses and broad-leaved weeds in rice, whereas B42) is a urea having a particularly pronounced activity against cyperaceae and annual grasses in rice, but also against dicotyledonous plants

Compositions with excellent activity are obtained when B39) and/or B42) are contained in the composition according to the invention as combination partners of type Bc), and it is then possible to control even particularly resistant harmful plants and even undesirable plants which are resistant against customary compositions in an excellent manner.

A fourth subgroup of compounds which, when admixed with compounds of type A, permit the production of herbicidal compositions having excellent properties is the subgroup Bd) of the herbicides which are selective in rice against grasses and dicotyledonous plants/cyperaceae. Type B substances having this activity profile are preferably found in the chemical substance classes of the 2,6-dinitroanilines, pyrazoles, pyrimidinyloxobenzoic acids, oxadiazoles, anilides, diphenyl ethers, alkylcarboxylic acids, of the sulfonylureas which are different from the sulfonylureas given in formula I, of the 1,3,5-triazines, pyridines and, surprisingly, even in the group of the organophosphorus compounds.

In another preferred embopdiment of the invention, the herbicidally active combinations comprise, as herbicides of type B, one or more herbicides which are selective in rice, mainly against grasses and dicotyledonous plants/cyperaceae, from the group consisting of B43)pendimethalin

Of particular importance in the group Bd) are, inter alia, the 2,6-dinitroanilines, such as pendimethalin (B43)) and clomazone (B44)).

However, the pyrazoles (B45)-B47)) and the pyrimidinyloxobenzoic acids, for example B48) or B49) are also noteworthy here.

The pyrazoles B45) to B47) permit combinations with an excellent activity spectrum. B45) emphasizes the control of perennial broad-leaved weeds in rice, combinations with B46) have proved to be particularly useful against grasses and seeds in rice such as Potamogeton distinctus, Sagittaria trifolium, Alisma canaliculatum etc., and combinations which, in addition to at least one type A compound, comprise the compound B47) permit a virtually complete suppression of annual and perennial weeds in rice, both of the cyperaceae and of the dicotyledonous plants or grasses.

Combinations with B48) are also particularly advantageous for controlling Echinochloa spp. in “direct-seeded” rice, whereas the activity of combinations which comprise B49) as a component is noticeable, inter alia in a particularly favorable manner against Echinochloa spp. in paddy rice.

Of special interest are also combinations of the group Bd) with oxadiazoles, anilides, diphenyl ethers or alkylcarboxylic acids.

In the context of the invention, the combinations with oxadiazoles, such as, for example, B50) or B51) have proved to be very useful in particular against annual broad-leaved weeds and weed grasses by the pre-emergence method and of the same weeds by the post-emergence method. In particular, combinations with oxadiargyl (B51)) control in an excellent manner Amaranthus, Bidens, Chenopodium, Malva, Monochoria, Polygonum, Portulaca, Potamogeton, Raphanus, Solanum, Sonchus and Rotala among the broad-leaved weeds and Echinochloa, Leptochloa, Brachiaria, Cenchrus, Digitaria, Eleusine, Panicum and wild rice among the weed grasses, and also of annual seeds, both by the pre-emergence and, in some cases, by the post-emergence method.

Anilides, such as the chloroacetanilide B52) or B53), and the sulfoanilides, for example B54), also have to be emphasized as being useful combination partners for the type A compounds. Here, the anilides exhibit complementary activity among the annual grasses and broad-leaved weeds, in particular against Gallium aparine, Stellaria media, all kinds of Brassicaceae and also Chenopodium spp., Amaranthus retroflexus, Solanum nigrum and Polygonum persicaria, in each case in particular also by the post-emergence method.

Finally, diphenyl ethers or arylcarboxylic acids are also interesting partners for the type A sulfonylureas. The diphenyl ether B55) helps in closing activity gaps which may be present among the grasses and broad-leaved weeds. B56) has an enhancing effect in particular in the control of halophytic and semiaquatic weed grasses.

In the context of the invention, particularly advantageous mixtures result when, as type B compounds, the combination according to the invention comprises the combination partners from the group Bd) which feature in the experiments.

In a further preferred embodiment of the invention, the herbicidally active combinations comprise, as herbicides of type B, one or more herbicides which are selective in rice against grasses and dicotyledonous plants and cyperaceae from the group consisting of

The compounds B57) to B65) are certain sulfonylureas whose selection and suitability is critical for the combinations according to the invention. They are structurally different from the sulfonylureas of the formula I. All of them give, together with partners of type A, excellent combinations having high selectivity in rice and activity against grasses, cyperaceae and dicotyledonous harmful plants. Frequently, it is possible, by selecting a suitable type B compound, to influence the spectrum of harmful plants that is mainly controlled by the combinations according to the invention in a targeted manner.

Thus, sulfonylureas B57) or B58) give combinations having high selectivity against annual and perennial weeds in rice, such as: Butomus umbellatus, Scirpus maritimus, Scirpus mucronatus, Alisma plantago-aquatica, Alisma lanceolatum, Sparganium erectum, Cyperus spp., Typha spp.

The activity spectrum of combinations with sulfonylurea B59) includes mainly the selective control of annual and perennial broad-leaved weeds, seeds and grasses (barnyard grass) in rice, whereas B60) has its main activity against Alisma, annual Cyperus, Elocharia, Marsilea, Potamogeton and Sagittaria spp., Monochoria vaginalis and Sphenoclea zeylanica.

Combinations according to the invention with sulfonylurea B61) have proved to have high selectivity against annual and perennial broad-leaved weeds and seeds in rice, whereas B62) is selective against Cyperus serotinus, Eleocharis kuroguwai, Sagittaria pygmaea and similar weeds in rice.

Combinations according to the invention with phenoxy-sulfonylureas B63) can serve to close activity gaps in the range of mono- and dicotyledonous weeds in rice, similarly to mixtures with B64) and/or B65).

Of particular interest are, especially, also herbicidal compositions with sulfonylureas which are selective in rice against dicotyledonous plants, cyperaceae and grasses for which biological data are given in the Example Section.

Of relatively great importance are furthermore, from the group Bd), the 1,3,5-triazines, pyridines, organo-phosphorus compounds, and other individual representatives of certain chemical substance classes, for use in combinations according to the invention.

In another preferred embodiment of the invention, the herbicidally active combinations comprise, as herbicides of type B, one or more herbicides which are selective in rice against grasses and dicotyledonous plants and cyperaceae, from the group consisting of

-   B66) prometryn     -   N², N⁴-diisopropyl-6-methylthio-1,3,5-triazine-2,4-diamine,         Pesticide Manual, 11th Ed. 1997, pp.1011-1013, -   B67) simetryn     -   N², N⁴-diethyl-6-methylthio-1,3,5-triazine-2,4-diamine, where         the compound B67) is known, inter alia, from Pesticide Manual,         11th Ed. 1997, pp.1108-1109, -   B68) thiazopyr     -   methyl         2-difluoromethyl-5-(4,5-dihydro-1,3-thiazolyl)-6-trifluoromethylnicotinate,         where the compound B68) is known, inter alia, from Pesticide         Manual, 11th Ed. 1997, pp.1185-1187; -   B69) pyrazophos     -   ethyl         2-diethoxyphosphinothioyloxy-5-methylpyrazolo-[1,5-a]pyrimidine-6-carboxylate,         where the compound B69) is known, inter alia, from Pesticide         Manual, 11th Ed. 1997, pp.1050-1052, -   B70) pentoxazone     -   3-(4-chloro-5-cyclopentyloxy-2-fluorophenyl)-5-iso-propylidene-1,3-oxazolidine-2,4-dione,         where the compound B70) is known, inter alia, from Pesticide         Manual, 11th Ed. 1997, pp.942-943, -   B71) indanofan     -   (RS)-2-[2-(3-chlorophenyl)-2,3-epoxypropyl]-2-ethyl-indane-1,3-dione,         where the compound B71) is known, inter alia, from Pesticide         Manual, 11th Ed. 1997, p.715, -   B72) LGC-40863=pyribenzoxim     -   introduced at the Brighton Crop Protection Conference Weeds         1997,         and -   B73) MY100=oxaziclomefone

The compounds B1) to B73) are selective herbicides in rice and transgenic rice which are known, for example, from the source given at the respective compound and which are used in combination specifically with the A compounds of the invention. In addition to the parent substance, the formula of which is in each case given for clarity, modifications of the parent substances which are customarily employed are in some cases also referred to.

In particular, all modifications of the B compounds which are customarily employed are part of the present invention, even if they are not expressly mentioned individually. If optically active forms of the type B compounds are customary, these also form part of the invention, and in some cases these forms were also referred to (for example fenoxaprop-ethyl and fenoxaprop-P-ethyl etc.).

Combinations of the active compounds A+B have superadditive effects, i.e. using the herbicidal compositions according to the invention as it is possible, with the same control of the harmful plants, to reduce the application rate and/or to increase the safety margin in rice crops. Both make sense, from an economical as well as ecological point of view. The amounts of components A+B to be employed, the ratio of the components A:B and the order in which the components are applied depend, like, for example, the formulation that is to be chosen, on a whole range of factors.

In this context, the type of mixing partner, the development stage of the broad-leaved weeds or weed grasses, the weed spectrum to be controlled, environmental factors, climatic conditions, soil conditions, etc., have to be taken into consideration.

In a very particularly preferred embodiment according to the invention, the herbicidal compositions according to the invention comprise a synergistically effective amount of a combination of the compounds of the formula I or their salts (type A compounds) with compounds from group B. Here, it has to be particularly emphasized that even in combinations with application rates or ratios by weight of A:B in which a synergism cannot in all cases be detected without any problems—for example because the individual compounds are usually employed in the combination at very different application rates or because the control of the harmful plants by the individual compounds is already very good—the herbicidal compositions of the invention usually have an inherent synergistic action.

The application rates of the herbicide A are generally between 0.1 and 100 g of ai/ha (ai=active ingredients, i.e. application rate based on the active compound), preferably between 0.5 and 60 g of ai/ha, very particularly preferably between 2 and 40 g of ai/ha.

With respect to the specific subgroups Aa) and Ab), the application rates of compounds of type A are usually:

Application rates g of ai/ha Type A compounds standard preferred Aa) 0.1 to 10 0.5 to 5 Sulfonylureas of the formula I in rice {e.g. A1) or A1*)} Ab)   2 to 40   5 to 25 Sulfonylureas of the formula I in rice {e.g. A2) or A3)}

Particularly surprising is the extremely low application rate of the sulfonylureas of the formula I from subgroup Aa). The application rate, for example of the compound A1) or A1*), is reduced again drastically, compared with the application rate known for the use of A1) or A1*) for controlling harmful plants in cereals or maize. This particularly low application rate, with an unchanged or better control of harmful plants in the control of harmful plants in rice, was, based on the prior art, unforeseeable.

The application rates of compounds of type B are usually:

The ratios by weight of A:B of the combined herbicides can, as already mentioned, vary within wide limits, like their application rates. A range of the ratios of the application rates (wt/wt) according to the invention includes, for example, A:B from 1:20,000 to about 200:1. In the context of the invention, preference is given to compositions which comprise compounds of the formula I or their salts (type A compounds) and compounds from group B in a weight ratio of about 1:8000 to 100:1.

The active compound combinations according to the invention can be present both as a mix of the two components, in which case they are applied in a customary manner diluted with water, or they can also be prepared as a so-called tank mix by joint dilution of the separately formulated components with water.

The active compounds of types A and B can be formulated in various ways, depending on the prevailing biological and/or chemicophysical parameters.

The following possibilities are suitable formulations:

Wettable powders (WP), emulsifiable concentrates (EC), water-soluble powders (SP), water-soluble concentrates (SL), concentrated emulsions (EW), such as oil in-water and water-in-oil emulsions, sprayable solutions or emulsions, capsule suspensions (CS), oil- or water-based dispersions (SC), suspoemulsions, suspension concentrates, dusts (DP), oil-miscible solutions, seed dressings, granules (GR) in the form of microgranules, spray granules, coated granules and absorption granules, granules for broadcasting and soil application, water-soluble granules (SG), water-dispersible granules (WG), ULV formulations, microcapsules and waxes.

Among these, preference is given to water-soluble wettable powders (WP), water-dispersible granules (WG), water-emulsifiable granules (EC), suspoemulsions (SE) and oil-suspension concentrates (SC).

These individual types of formulation are known in principle and are described, for example, in: Winnacker-Kuchler, “Chemische Technologie” [Chemical Technology], volume 7, C. Hauser Verlag, Munich, 4th Ed. 1986; Wade van Valkenburg, “Pesticide Formulations”, Marcel Dekker N. Y., 1973; K. Martens, “Spray Drying Handbook”, 3rd Ed. 1979, G. Goodwin Ltd. London.

The formulation auxiliaries required, such as inert materials, surfactants, solvents and other additives are also known and are described, for example, in: Watkins, “Handbook of Insecticide Dust Diluents and Carriers”, 2nd Ed., Darland Books, Caldwell N. J.; H. v. Olphen “Introduction to Clay Colloid Chemistry”, 2nd Ed., J. Wiley & Sons, N. Y.; Marsden “Solvents Guide”, 2nd Ed., Interscience, N. Y. 1963; McCutcheon's “Detergents and Emulsifiers Annual”, MC Publ. Corp., Ridgewood N. J.; Sisley and Wood, “Encyclopedia of Surface Active Agents”, Chem. Publ. Co. Inc., N. Y. 1964; Schonfeldt, “Grenzflachenaktive Athylenoxidaddukte”, [Surface-active ethylene oxide adducts], Wiss. Verlagsgesellschaft, Stuttgart 1976; Winnacker-Kuchler “Chemische Technologie”, [Chemical Technology], Volume 7, C. Hauser Verlag Munich, 4th Ed. 1986.

Based on these formulations, it is also possible to prepare combinations with pesticidally active compounds, herbicides, insecticides, fungicides, and also antidotes, safeners, fertilizers and/or growth regulators, for example in the form of a ready mix or a tank mix.

The herbicide combinations of the invention are prepared particularly advantageously by formulating the compounds of the formula I or salts thereof (type A compounds) with one or more compounds of type B similar to a conventional crop protection formulation from the group consisting of water-soluble wettable powders (WP), water-dispersible granules (WDG), water-emulsifiable granules (WEG), suspoemulsions (SE) and oil suspension concentrates (SC).

Wettable powders are preparations which are uniformly dispersible in water and which, besides the active compounds, also comprise ionic and/or nonionic surfactants (wetting agents, dispersants), for example polyethoxylated alkylphenols, polyethoxylated fatty alcohols, polyethoxylated fatty amines, fatty alcohol polyglycol ether sulfates, alkanesulfonates or alkylarylsulfonates, sodium lignosulfonate, sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, sodium dibutylnaphthalenesulfonate or else sodium oleoylmethyltaurinate, in addition to a diluent or inert substance.

Emulsifiable concentrates are prepared by dissolving the active compound or active compounds in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene, or else higher-boiling aromatics or hydrocarbons with the addition of one or more ionic and/or nonionic surfactants (emulsifiers). Examples of emulsifiers which can be used are: calcium salts of alkylarylsulfonic acids, such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensates (for example block copolymers), alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or other polyoxyethylene sorbitan esters.

Dusts are obtained by grinding the active compound or the active compounds with finely divided substances, for example talc, natural clays such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.

Granules can be prepared either by spraying the active compound or the active compounds onto adsorptive granulated inert material or by applying active compound concentrates to the surface of carriers such as sand, kaolinites or of granulated inert material by means of binders, for example polyvinyl alcohol, sodium polyacrylate or else mineral oils.

Water-dispersible granules are generally prepared by the customary processes such as spray drying, fluidized-bed granulation, disk granulation, mixing with high-speed mixers and extrusion without solid inert material. It is also possible to granulate suitable active compounds in the manner customarily used for preparing fertilizer granules—if appropriate in a mixture with fertilizers.

Generally, the agrochemical preparations according to the invention comprise 0.1 to 99% by weight, in particular 2 to 95% by weight, very particularly 3 to 92% by weight, of active compounds of types A and B, in addition to customary formulation auxiliaries.

The concentrations of the active compounds A+B in the formulations may vary. In wettable powders, the active compound concentration is, for example, approximately 10 to 95% by weight, the remainder to 100% by weight being composed of customary formulation components. In the case of emulsifiable concentrates, the active compound concentration may amount to approximately 1 to 85% by weight, preferably 5 to 80% by weight. Formulations in the form of dusts comprise approximately 1 to 25% by weight, in most cases 5 to 20% by weight, of active compounds, and sprayable solutions comprise approximately 0.2 to 25% by weight, preferably 2 to 20% by weight, of active compounds. The active compound content of granules such as dispersible granules depends partly on whether the active compound is in liquid or solid form and on which granulation auxiliaries and fillers are being used. In general, the content of the water-dispersible granules amounts to between 10 and 90% by weight.

In addition, the abovementioned active compound formulations comprise, if appropriate, the tackifiers, wetting agents, dispersants, emulsifiers, penetrants, preservatives, antifreeze agents, solvents, fillers, colorants, carriers, antifoams, evaporation inhibitors and pH and viscosity regulators which are customary in each case.

Owing to the relatively low application rate of the combinations of A+B according to the invention, they are generally already very well tolerated. In particular, the combinations according to the invention permit a reduction of the absolute application rate, compared with the individual application of a herbicidally active compound. However, to increase the tolerability and/or selectivity of the herbicide combinations according to the invention, if desired, even more, it is advantageous to apply these jointly in a mixture or successively at different times together with safeners or antidotes. Suitable safeners or antidotes for the combinations according to the invention are the compounds known, for example, from EP-A-333 131 (ZA-89/1960), EP-A-269 806, (U.S. Pat. No. 4,891,057), EP-A-346 620 (AU-A-89/34951) and the international patent applications PCT/EP 90/01966 (WO-91/08202) and PCT/EP 90/02020 (WO-91/078474) and the literature cited therein, or they can be prepared by the methods described therein. Further suitable safeners are known from EP-A-94 349 (U.S. Pat. No. 4,902,304), EP-A-191 736 (U.S. Pat. No. 4,881,966) and EP-A-0 492 366 and the literature cited therein.

In the most favorable case, the herbicidal mixtures or use combinations of the invention additionally comprise

The safeners (antidotes) of the above groups a) to j) (in particular compounds of the formulae C1, C2 and C3) reduce or neutralize phytotoxic effects which can occur when using the product combinations according to the invention in crops of useful plants, without adversely affecting the activity of the herbicides against harmful plants. Thus, it is possible to increase the area of use of the herbicide mixtures according to the invention considerably. In particular, the use of safeners permits the use of combinations which hitherto could be used only with limitations or without sufficient success, i.e. of combinations which, without safener, at low application rates with a narrow spectrum of activity did not provide sufficient control of the harmful plants.

The herbicidal mixtures according to the invention and said safeners can be applied together (in the form of a finished formulation or by the tank mix method) or in any desired sequence one after the other. The weight ratio safener:herbicide (group A, i.e. compounds of the formula I) can vary within wide limits and is preferably in the range from 1:100 to 100:1, in particular from 1:100 to 50:1. The amounts of herbicides (type A and type B compounds) and safener which are optimal in each case depend on the type of herbicide mixture used and/or on the safener used and on the nature of the plants to be treated.

Depending on their properties, the safeners of type C) can be used for pretreating the seed of the crop plant (seed dressing) or be incorporated into the seed furrows before seeding or used together with the herbicide mixture before or after the plants have emerged. Pre-emergence treatment includes treatment of the area under cultivation before seeding and also treatment of those areas under cultivation which have been seeded but where growth has not yet taken place. Application together with the herbicide mixture is preferred. Tank mixtures or finish formulations can be used for this purpose.

The required application rates of safeners can vary within wide limits, depending on the indication and the herbicide used, and are generally in the range from 0.001 to 1 kg, preferably 0.005 to 0.2 kg, of active compound per hectare.

Particularly favorable herbicidal compositions which are extremely suitable for use in rice are obtained in the context of the invention when herbicides from group Aa) are used in combination with type B compounds and the safener ethyl 5,5-diphenyl-2-isoxazoline-3-carboxylate (=compound C3-1)).

For this case, it has surprisingly been found that combinations of type A compounds and the safener C3-1) exhibit superadditive, quasi-synergistic activity in rice even without the addition of another standard herbicide from group B. This highly favorable effect permits a further decrease of the application rates, at an unchanged high and broadly effective control. This is preferably true for combinations of compounds of group Aa).

A particularly favorable combination is the joint use of A1) or A1*) and C3-1 with at least one type B compound.

In this case, the safener C3), in particular C3-1, acts particularly advantageously in two ways, both by protecting the rice crops against undesirable damage by the type A herbicides and by the synergistic increase of the activity of the individual herbicides from group A.

Of particular interest for the invention are herbicidal compositions which comprise the type A compounds in an amount of 0.5 to 60 g of ai/ha in combination with the safener C3) in an amount of 10 to 200 g of ai/ha.

Herbicidal compositions which have a weight ratio of type A compounds:C3) in the range from 1:400 to 20:1, preferably 1:200 to 10:1, are likewise favorable.

A particular embodiment of the invention also relates to herbicidal compositions which comprise a type A compound, preferably the compound A1) or A1*), in an amount of 0.1 to 10 g of ai/ha in combination with C3) in an amount of 10-100 g of ai/ha.

For use, the formulations, which are in commercially available form, are, if appropriate, diluted in the customary manner, for example using water in the case of wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules. Preparations in the form of dusts, granules for soil application or for broadcasting and sprayable solutions are usually not diluted further with additional inert substances prior to use.

The invention also relates to a method for controlling undesirable plants which comprises applying a herbicidally effective amount of a combination of active compounds A+B according to the invention to these plants or to the area under cultivation. The active compounds can be applied to the plants, to parts of plants, plant seeds or to the area under cultivation.

In a preferred variant of the method, the compounds of the formula (I) or salts thereof (type A compounds) are applied at application rates of from 0.1 to 100 g of ai/ha, preferably from 0.5 to 60 g of ai/ha, very particularly preferably between 2 and 40 g of ai/ha, while the application rates for the compounds of type B are from 1 to 5000 g of ai/ha. Preference is given to applying the active compounds of types A and B simultaneously or at different times at a weight ratio of 1:20,000 to 200:1. Furthermore, particular preference is given to the joint application of the active compounds in the form of tank mixtures, the optimally formulated concentrated formulations of the individual active compounds being mixed together in the tank with water and the resulting spray liquor being applied.

Since the combinations according to the invention provide extremely good crop safety and at the same time very efficient control of harmful plants, they can be considered to be selective. In a preferred variation of the method, herbicidal compositions comprising the active compound combinations according to the invention are therefore employed for selective control of undesirable plants.

The method for the selective control of harmful plants using the combination partners of type B) from subgroups Ba) to Bd) is particularly advantageous when the herbicidal compositions of the invention are employed in rice.

The combination partners of type A, applied on their own in rice already control a relatively wide range of annual and perennial broad-leaved weeds, weed grasses and Cyperaceae.

Combination with the type B partners mentioned in the invention improves the activity spectrum of the type A compounds even further.

Thus, the compounds B1) to B27) from group Ba) complement and enhance, inter alia, the activity in the control of grass weeds in rice.

Most of the combination partners B28) to B33) from the group Bb) belong to the growth-regulating herbicides which complement and enhance the activity of the type A compounds in rice, in particular when controlling weeds from the spectrum of the dicotyledonous plants, but also considerably against cyperaceae.

The compounds from the subgroup Bc) (for example B39) to B42)) are widely used active compounds which can be employed for increasing the activity of the type A compounds when controlling mainly cyperaceae especially in rice.

The azoles and pyrazoles from the subgroup Bd) (for example B46) and B47)) can be used particularly advantageously at comparatively low application rates for controlling dicotyledonous weeds in rice. However, they are also particularly effective against a broad spectrum of harmful grasses, just as they control cyperaceae.

A comparable spectrum of harmful plants is controlled by the compounds from the group of the sulfonylureas (compounds B57) to B65)), but the application rates are lower by about another order of magnitude.

Depending on the nature of the combination partner B, the herbicidal combinations according to the invention can be used advantageously for controlling undesirable plants even in transgenic rice crops.

Transgenic crops are those in which the plants have been made resistant to herbicides or pesticides by genetic manipulation. Such modified rice crop plants then allow a selective use.

Overall, the invention thus also relates to the use of herbicidal compositions comprising

-   A) at least one herbicidally active compound from the group of the     substituted phenylsulfonylureas of the formula I and their     agriculturally accepted, i.e. acceptable and compatible, salts     in which     -   R¹ is (C₁-C₈)-alkyl, (C₃-C₄)-alkenyl, (C₃-C₄)-alkynyl or         (C₁-C₄)-alkyl, which is mono- to tetrasubstituted by radicals         from the group consisting of halogen and/or (C₁-C₂)-alkoxy;     -   R² is I or CH₂NHSO₂CH₃;     -   R³ is methyl or methoxy; and     -   Z is N or CH;         and -   B) at least one herbicidally active compound from the group of the     compounds consisting of -   Ba) herbicides which are selective in rice, mainly against grasses,     selected from the group consisting of B1)butachlor, B2)butenachlor,     B3)thenylchlor, B4)pretilachlor, B5)mefenacet, B5a)Bay FOE 5043,     B6)naproanilid, B7)propanil, B8)etobenzanid, B9)dimepiperate,     B10)molinate, B11)thiobencarb, B12)pyributicarb, B13)quinclorac,     B14a)sulcotrione, B15)cycloxydim, B16)sethoxydim, B17)NBA 061     fentrazamid, B18)piperophos, B19)anilofos, B20)fenoxaprop,     fenoxaprop-P, B21)haloxyfop, B22)cyhalofop, B23)JC-940,     B24)dithiopyr, B25)bromobutide, B26)cinmethylin and B27)CH-900, -   Bb) herbicides which are selective in rice, mainly against     dicotyledonous harmful plants and cyperaceae, selected from the     group consisting of B28)2,4-D, B29)mecoprop, mecoprop-P, B30)MCPA,     B31)dicamba, B32)acifluorfen, B33a)     -   B34)chlorimuron, B35)triasulfuron, B36)ioxynil, B37)picloram and         B38)carfentrazon, -   Bc) herbicides which are selective in rice, mainly against     cyperaceae selected from the group consisting of B39)bentazon,     B40)triclopyr, B41)benfuresate and B42)daimuron, and -   Bd) herbicides which are selective in rice, mainly against grasses     and dicotyledonous harmful plants and harmful cyperaceae plants,     selected from the group consisting of B43)pendimethalin,     B44)clomazon, B45)benzofenap, B46)pyrazolynate, B47)pyrazoxyfen,     B48)KIH 2023, B49)KIH 6127, B50)oxadiazon, B51)oxadiargyl,     B52)acetochlor, B53)metolachlor, B54)metosulam, B55)oxyfluorfen     B56)dalapon, B57)metsulfuron, B58)bensulfuron, B59)pyrazosulfuron,     B60)cinosulfuron, B61)imazosulfuron, B62)AC 322,140     (cyclosulfamuron), B63a)ethoxysulfuron (HOE 095404),     B64)azimsulfuron (DPX-A8947), B65)nicosulfuron, B66)prometryn,     B67)simetryn, B68)thiazopyr, B69)pyrazophos, B70)pentoxazone,     B71)indanofan, B72)LGC 40863 and B73)MY 100,     -   in a weight ratio of compounds of the formula I or salts thereof         (type A compounds) and compounds from group B in the range from         1:20,000 to 200:1, preferably 1:8000 to 100:1, particularly         preferably 1:4000 to 50:1, for controlling undesirable harmful         plants in crops of rice.

The use of a safener in the abovementioned combinations offers considerable advantages, since it reduces possible damage to the crop plant rice which may be caused by sulfonylurea derivatives or other herbicidally active compounds.

The abovementioned active compound combinations can easily be varied.

On the one hand, the compounds of the formulae A1 and/or A1 *, A2 or A3 can be replaced by other compounds of the formula I, without the resulting combinations being considerably worse. Rather, the substance mixture present is still essentially synergistically active.

On the other hand, it is likewise possible to replace the sulfonylurea B63a (ethoxysulfuron) in the listed combinations by one or more of the following sulfonylureas:

-   B57) metsulfuron; -   B58) bensulfuron; -   B59) pyrazosulfuron; -   B60) cinosulfuron; -   B61) imazosulfuron; -   B62) cyclosulfamuron; -   B64) azimsulfuron; -   B65) nicosulfuron.

Particularly preferred multicomponent combinations comprise two or more of the sulfonylureas of type B. These include, inter alia:

The abovementioned combinations can also optionally be improved by adding the safener C3-1.

It may also be advantageous to replace the safener compound C2-1 by or to use the safener compound C2-1 together with one or more herbicides having safener action and/or safeners. This applies in a similar manner to the safener C3-1.

Thus, in the abovementioned combinations, daimuron (B42)) and/or quinclorac (B13)) can additionally improve the herbicidal activity against cyperus spp. and grasses, and/or they can replace some or all of the safener C2-1.

Furthermore, the safener C2-1 can advantageously be replaced by or used together with one or more of the compounds from the following group:

-   ethyl     1-(2,4-dichlorophenyl)-5-(ethoxycarbonyl)-5-methyl-2-pyrazoline-3-carboxylate     (C1-1), -   ethyl 1-(2,4-dichlorophenyl)-5-methylpyrazole-3-carboxylate (C1-2), -   ethyl 1-(2,4-dichlorophenyl)-5-isopropylpyrazole-3-carboxylate     (C1-3), -   ethyl     1-(2,4-dichlorophenyl)-5-(1,1-dimethylethyl)-pyrazole-3-carboxylate     (C1-4), -   ethyl 1-(2,4-dichlorophenyl)-5-phenylpyrazole-3-carboxylate (C1-5), -   ethyl     1-(2,4-dichlorophenyl)-5-trichloromethyl-(1H)-1,2,4-triazole-3-carboxylate     (C1-6, fenchlorazol) -   ethyl 5-(2,4-dichlorobenzyl)-2-isoxazolin-3-carboxylate (C1-7), -   ethyl 5-phenyl-2-isoxazoline-3-carboxylate (C1-8), -   1,3-dimethylbut-1-yl (5-chloroquinolin-8-yloxy)acetate (C2-2), -   4-allyloxybutyl (5-chloroquinolin-8-yloxy)acetate (C2-3), -   1-allyloxyprop-2-yl (5-chloroquinolin-8-yloxy)acetate (C2-4), -   ethyl (5-chloroquinolin-8-yloxy)acetate (C2-5), -   methyl (5-chloroquinolin-8-yloxy)acetate (C2-6), -   allyl (5-chloroquinolin-8-yloxy)acetate (C2-7), -   2-(2-propylideneiminooxy)-1-ethyl (5-chloroquinolin-8-yloxy)acetate     (C2-8), -   2-oxoprop-1-yl (5-chloroquinolin-8-yloxy)acetate (C2-9), -   diethyl (5-chloroquinolin-8-yloxy)malonate, -   diallyl (5-chloroquinolin-8-yloxy)malonate, -   methyl ethyl (5-chloroquinolin-8-yloxy)malonate, -   2,4-dichlorophenoxyacetic acid (ester) (2,4-D), -   2-(4-chloro-2-methylphenoxy)propionic ester (mecoprop), -   MCPA, -   3,6-dichloro-2-methoxybenzoic acid (ester) (dicamba) and -   ethyl 5,5-diphenyl-2-isoxazoline-3-carboxylate (C3-1).

This results in numerous possibilities of combining two or more active compounds with one another and to use them together for controlling weeds in rice crops without deviating from the essence of the invention.

The herbicidal compositions (combinations) according to the invention have excellent herbicidal activity against a broad spectrum of economically important mono- and dicotyledonous harmful plants. Even perennial weeds which sprout from rhizomes, stem-tubors or other permanent organs and which are difficult to control are covered well by the active compound combinations. Here, it is immaterial whether the substances are applied by the presowing, the preemergence or the post-emergence method.

Among the monocotyledonous weed species, echinochloa and cyperus species from the annual group and permanent cyperus species from among the perennial species, for example, are covered well.

The active compound combinations according to the invention control weeds which are encountered under the specific cultivation conditions in rice, such as, for example, sagittaria, alisma, rotala, monochoria, eleocharis, scirpus, cyperus, etc., very efficiently.

If the herbicidal compositions according to the invention are applied before germination, the emergence of the weed seedlings is either prevented completely, or the weeds grow until they have reached the cotyledon stage, after which they stop to grow and finally die off completely after three to four weeks have passed.

When the active compound combination of the invention is applied to the green parts of the plant by the post-emergence method, the growth is likewise stopped drastically shortly after the treatment. The weed plants remain at the growth stage that they have reached at the time of application, or they die off more or less quickly after a certain period of time, so that it is possible in this manner to eliminate weed competition, which is harmful to crop plants, at a very early stage and lasting by using the novel compositions according to the invention.

Although the compositions according to the invention have excellent herbicidal activity against mono- and dicotyledonous weeds, the crop plant is damaged to a negligible extent, if at all. For this reason, the compositions are highly suitable for selectively controlling undesirable plant growth, especially in rice.

As already mentioned, the harmful plants to be controlled include, specifically, especially grasses, dicotyledonous plants and/or cyperaceae which are otherwise difficult to control. Harmful plants which are, to be controlled preferably with the combinations of type A and type B compounds according to the invention include, inter alia, Echinochloa colonum, Echinochloa chinesis, Echinochloa crus galli, Leptochloa chin./fil., Paspalum dis., Brachiaria platyphylla, Digitaria spp., Ischaemum, Leersia hexandra, Oryza sativa (Red rice), Cenchrus echinatus, Rottboellia exaltata, Leersia and the like from among the grasses, Monochoria vag., Potamogeton dis., Rotala indica, Marsilea crenata, Ludwigia ad., Salvina mol., Ipomoea, Sesbania ex., Heteranthera, Commelinia, Butomus, Aeschynomene, Alisma plantago, Eclypta, Murdania, Xanthium, Alteranthera spp., Spenodea zey., Sagittaria, luncus spp., Polygonum, Ammania ind. from among the weeds and Cyperus diff., Cyperus iria, Fimbristylis litt., Cyperus ferax, Cyperus esculentes from among the annuals cyperaceae and also Eleocharis spp., Scirpus spp., Scirpus mucronatus and Cyperus rotundus from among the perennial cyperaceae.

In summary, it may be stated that superadditive (synergistic) effects are achieved when sulfonylureas of the formula I and/or their salts are used together wtih one or more active compounds from group B. The activity in the combinations is more pronounced than that of the individual products used employed alone.

These effects permit

-   the application rate to be reduced, -   a broader spectrum of broad-leaved weeds and weed grasses to be     controlled, -   a more rapid and safer action, -   a more prolonged action, -   complete control of harmful plants with only one or few applications     and -   a widening of the period of time when the active compounds in the     combination can be applied.

The abovementioned properties are required in weed control practice to keep agricultural crops free from undesirable competing plants and thus to ensure and/or increase yields from a qualitative and quantitative point of view. The combinations according to the invention markedly surpass the prior art with a view to the above-described properties.

Additionally, the combinations according to the invention permit the outstanding control of otherwise resistant harmful plants.

The following examples serve to illustrate the invention:

1. FORMULATION EXAMPLES

-   a) A dust is obtained by mixing 10 parts by weight of an active     compound combination according to the invention and 90 parts by     weight of talc as inert substance and comminuting the mixture in a     hammer mill. -   b) A wettable powder which is readily dispersible in water is     obtained by mixing 25 parts by weight of active compounds A+B, 64     parts by weight of kaolin-containing quartz as inert substance, 10     parts by weight of potassium ligninsulfonate and 1 part by weight of     sodium oleoylmethyltaurate as wetting agent and dispersant, and     grinding the mixture in a pinned-disk mill. -   c) A dispersion concentrate which is readily dispersible in water is     obtained by mixing 20 parts by weight of active compounds A +B with     6 parts by weight of alkylphenol polyglycol ether (®Triton X 207), 3     parts by weight of isotridecanol polyglycol ether (8 EO) and 71     parts by weight of paraffinic mineral oil (boiling range for example     approximately 255 to 277° C.), and grinding the mixture in a ball     mill to a fineness of below 5 microns. -   d) An emulsifiable concentrate is obtained from 15 parts by weight     of cyclohexanone as solvent and 10 parts by weight of ethoxylated     nonylphenol as emulsifier. -   e) Water-dispersible granules are obtained by mixing 75 parts by     weight of active compounds A+B, 10 parts by weight of calcium     lignosulfonate, 5 parts by weight of sodium lauryl sulfate, 3 parts     by weight of polyvinyl alcohol and 7 parts by weight of kaolin,     grinding the mixture in a pinned-disk mill and granulating the     powder in a fluidized bed by spraying on water as granulation     liquid. -   f) Water-dispersible granules are also obtained by homogenizing, in     a colloid mill, 25 parts by weight of active compounds A+B, 5 parts     by weight of sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, 2 parts     by weight of sodium oleoylmethyltaurate, 1 part by weight of     polyvinyl alcohol, 17 parts by weight of calcium carbonate and 50     parts by weight of water, precomminuting the mixture, subsequently     grinding it in a bead mill and atomizing and drying the resulting     suspension in a spray tower by means of a single-substance nozzle. -   g) Extruder granules are obtained by mixing and grinding 20 parts by     weight of active compounds A+B, 3 parts by weight of sodium     lignosulfonate, 1 part by weight of carboxymethylcellulose and 76     parts by weight of kaolin and moistening the mixture with water.     This mixture is extruded and subsequently dried in a stream of air.

2. BIOLOGICAL EXAMPLES

The examples mentioned below were carried out in the greenhouse, and in some instances, in field trials.

i) Pre-emergence Action Against Weeds

Seeds or rhizome pieces of mono- and dicotyledonous weed plants are placed into sandy loam soil in plastic pots having a diameter of 9 cm and are covered with soil. Weeds which are encountered in the cultivation of rice are cultivated in the soil which is saturated with water, the amount of water that is filled into the pots being such that the water level reaches the surface of the soil or is some millimeters above the soil surface. The active compound combinations according to the invention, formulated in the form of wettable powders or emulsion concentrates, and in parallel experiments the correspondingly formulated individual active compounds are then applied as aqueous suspensions or as emulsions in an amount of water of 300 to 600 l/ha (converted), at different dosages, onto the surface of the soil cover, or they are, in the case of rice, poured into the water used for irrigation.

After the treatment, the pots are placed in a greenhouse under good growth conditions (temperature, atmospheric humidity, water supply) for the weeds. Visual evaluation of the plants or the emergence damage was carried out after the test plants had emerged after a test period of 3 to 4 weeks, in comparison to untreated controls. The experiments are designed statistically, with several, up to five, repetitions. The herbicidal compositions according to the invention have good herbicidal pre-emergence activity against a broad spectrum of weed grasses and broad-leaved weeds.

ii) Post-emergence Activity Against Weeds

Seeds or rhizome pieces of mono- and dicotyledonous weed plants are placed into sandy loam soil in plastic pots, covered with soil and grown in a greenhouse under good growth conditions (temperature, atmospheric humidity, water supply). Weeds which are encountered in the cultivation of rice are cultivated in pots in which the water level is up to 2 cm over the soil surface. Three weeks after sowing, the test plants are treated at the three-leaf stage. The active compound combinations according to the invention, formulated as wettable powders or emulsion concentrates, and, in parallel experiments, the correspondingly formulated individual active compounds are sprayed onto the green parts of the plants at different dosages using an amount of water of 300 to 600 l/ha (converted), and, after about 3 to 4 weeks of the test plants in the greenhouse under optimum growth conditions (temperature, atmospheric humidity, water supply), the effect of the preparations is evaluated visually in comparison to untreated controls. In the case of rice or weeds which are encountered in the cultivation of rice, the active compounds are also added directly to the water for irrigation (application analogous to the so-called granules application) or sprayed onto plants and added to the water for irrigation. The experiments were designed with several, up to five, repetitions. The herbicidal compositions according to the invention also have good herbicidal post-emergence activity against a broad spectrum of economically important weed grasses and broad-leaved weeds.

iii) Evaluation of the Combination Effects in the Examples

For the assessment of the combination effects, the activity of the individual components was added and compared to the effect of the mixtures of the same dosage. In many cases, it became evident that the combinations had higher efficacies than the sum of the individual effects.

In cases with less pronounced effects, the expected value was calculated using Colby's formula and compared to the empirical result. The calculated expected theoretical efficacy of a combination is determined using the formula of S. R. Colby: “Calculation of synergistic and antagonistic responses of herbicide combinations”, Weeds 15 (1967), pages 20 to 22.

For combinations of two compounds, this formula is: $E = {X + Y - \frac{X \cdot Y}{100}}$ and, correspondingly, for combinations of three herbicidally active compounds: $E = {X + Y + Z + \frac{X \cdot Y \cdot Z}{10,000} - \frac{{X\quad Y} + {X\quad Z} + {Y\quad Z}}{100}}$ where

-   -   X=% damage by herbicide A at an application rate of x kg of         ai/ha;     -   Y=% damage by herbicide B at an application rate of y kg of         ai/ha;     -   Z=% damage by a further herbicide C at an application rate of z         kg of ai/ha;     -   E=expected value, i.e. expected damage by herbicides A+B (or         A+B+C) at x+y (or x+y+z) kg of ai/ha.

Synergistic effects were assumed to be present when the empirical value was greater than the expected value. Combinations of individual components of the same activity compounds could also be prepared by using the sum formula.

However, in most cases the synergistic increase in activity is so high that the Colby criterium can be dispensed with; in these cases, the activity of the combination considerably surpasses the formal (calculated) sum of the activities of the individual compounds.

Particular attention has to be drawn to the fact that when the synergism between the active compounds employed here is assessed, the highly different application rates of the individual active compounds have to be taken into consideration. Thus, it is not expedient to compare the activities of the active compound combinations and those of the individual active compounds in each case at identical application rates. The amounts of active compounds that can be saved according to the invention only become evident by the superadditive activity increase when the combined application rates are used, or by the reduction of the application rates of both individual active compounds in the combinations in comparison to the individual active compounds when the effect is in each case the same.
